Title: Oscillator for VHF TV receiver - has RL circuit ensuring synchronism between oscillator and receive frequency over entire tuning range
Inventor: REHM JOSEF
IPC: H03J3/28
Filed: 1978-10-31
Abstract: The oscillator circuit has a series circuit consisting of a capacitor(14) and a variable inductor(15) connected to a junction between the inductors(3, 4) in the oscillator resonant circuit(1) and to earth.

Title: Alternate substrate coating for capacitors - in glow discharge polymerisation chamber above metal evaporator chamber
Inventor: PACHONIK HORST DIPL PHYS
IPC: H01G4/14
Filed: 1979-01-29
Abstract: Substrates are coated in turn with metal and polymer layers to produce capacitor stacks in a vacuum vessel which is divided in two chambers. In the first, a high-tension potential is applied to the substrate and a monomer is admitted to produce a glow discharge polymerisation. The second chamber is divided by a shutter which can be withdrawn in the second stage to expose the substrate to the vapours from a metal evaporator. This requires only very simple apparatus and avoids any contact with air between the stages of the process.

Patent DE-2927866-A1 (DE)
Inventor: EDINGER EGON
IPC: H01F41/12
Filed: 1979-07-10
Abstract: In order to bake coils having a thermoplastic synthetic material sheath, a current surge is fed at a constant voltage through the coil which is correspondingly made contact with. The baking quality depends to a very large extent on the coil geometry, the heat dissipation on the coil and making contact with the coil wire ends. In order to obtain a uniform baking quality, in the case of the method according to the invention, the coil is heated by a plurality of heating current pulses, as a function of the heating of the coil. By means of the heating current (16), which is pulsed as a function of temperature, the coil can be baked for any desired length of time using the temperature response (15) which is optimum for it, to be precise distributed over the entire coil cross-section. <IMAGE>

Title: Low drag body for bobsleigh - has pivoted nose section contoured into rear section and with sliding seals
Inventor: RITTER FRANK-RUEDIGER
IPC: B62B17/06
Filed: 1979-12-21
Abstract: The bobsleigh with a low drag body has the nose section (13) pivoted about a central joint (16) so that its skids (75) can follow the curves or tilt independent of the rear skids (75).

The gap is covered with a sliding seal (94) and the vertical section through the joint is semicircular about the pivot joint (16). As the nose tilts to either side the drag factor is not increased. A spring holds the steering and tilt in the ahead position so that a self centering control is obtained.

IPC: G01N21/47
Filed: 1980-02-29
Abstract: Appts. for monitoring the fibre-orientation distribution in a moving web comprises a laser beam directed perpendicularly through the web into a detector which simultaneously measures the diffracted light in at least two different directions, preferably along the web and across the web. An electronic analyser compares the two measurements and output a signal which is proportional to the index of orientation of the fibres in the web. A separate section of the detector measures the intensity of the undiffracted light to give a continuous measurement of weight per unit area of the web. Device gives immediate and continuous measurements and can be used in prodn. to control the web-forming process on paper-making machinery, for example, or dry webs for textile processes.

Title: Erase facility for ink jet printer - uses electrode to generate aggressive plasma to neutralise ink
Inventor: DIETRICH KLAUS DR
IPC: B41J29/26
Filed: 1980-03-18
Abstract: An electrical technique is used to erase characters printed by a matrix print head of a jet printer. To erase an 'S' character printed on paper, electrodes (E1,E2) are positioned on either side. The electrodes are connected to a high voltage supply, e.g. 4,000V, over a resistor (R) and a control switch. When the switch is closed the air between the electrodes becomes ionised and through pulsed discharge a gas plasm is generated. The plasma constitutes an aggressive atmosphere that interacts with the printing ink to cause neutratisation.S Typically, the resistance has a value of 16 Mohm generating a current of 250 micro A. A variation is based upon multiple electrode pairs and a common centre electrode.

Title: Decorating method for spectacle frames - uses laser beam to melt coloured powder to form patterns etc. on metal-cored plastics-covered legs and rims
Inventor: ORTMEIER ERICH
IPC: G02C5/14
Filed: 1980-05-19
Abstract: The spectacle frames to be decorated are of the type made of a metal core with a plastics outer coating, and for adorning the ear pieces, side frames or lens edges, a coating powder is spread evenly over the surface, and locally pre-melted in selected patterns by means of a laser. The superfluous powder is blown off, and the frames placed in an oven to harden off the remaining pattern. It is only necessary to use low laser power to melt the electrostatically adhering powder, as this must not begin to evaporate, and the beam can be controlled in any desired direction or the frame moved in the X and Y plane. In this way, it is possible to create all types of patterns, and decorations, the base plastics coating obviously being differently coloured to the added melted pattern layer. To ensure good bonding, both plastics layers must be of the same type.
